EDI® Biax Film Dies for BOPE & BOPP Production

EDI® Biax Film Dies for BOPE & BOPP Production

Biax dies are customizable to meet each processor’s specific requirements. For added layer arrangement versatility, a variety of distribution block systems are available.   

Overview


Processors have long tried to solve the problem of ensuring their film is produced with consistent strength and durability, while also meeting the visual requirement dictated by the end product's use. To do this, the structural elements in the film must be proportionally extruded across its width. 

 

Delivering Uniform Film Structures

 

The uniform and precise layer-to-layer structure created by an EDI® die system means the film's integrity remains intact during stretching, creating an end product with exceptional protective qualities against chemical and environmental factors.

Ensure Consistent Film Properties Across the Width


It's no secret: inconsistent layer structures create weak points when the film is stretched. In an EDI® multi-manifold die system, each material is distributed in its own customized die flow channel prior to combination with the other layers. The layers then converge at full width, and shortly before exiting the die, reducing the chance of structural changes.

Save Material Costs


Biax film dies are designed for partial coverage, or a "naked edge," allowing processors to minimize the material at the edges of the film, where the tenter clips are used during the stretching process. This means less trim, thereby reducing costly material waste.

Product Testimonials

An EDI® nine-manifold flat die, the first of its kind, has been successfully commissioned, producing nine-layer film from various resins. While the degree of improvement will vary with the application, in general Nordson's nine-manifold die technology promises to reduce variation in individual layer thickness from the +/- 15% tolerance often encountered with comparably advanced feedblock systems to +/- 5%.
